In HTML and especially XML/XHTML/RSS the characters &, < , " must be
be replaced with entities (escaping). However, the canonical form of
a URL is without any entities. You would type in a browser
foo.php?a=b&c=d not foo.php?a=b&c=d. The second would produce two
arguments a=b and amp;c=d
I would guess that wp_insert_links is expected non-entity URLs, since
that I would expect that the web-page should escape the output of
get_link() as appropriate for the output medium.
I don't know enough about feedwordpress to know which one is at fault.
Isn't it strange that the same people that laugh at gypsy fortune tellers
take economists seriously?
